I have a Pioneer VSX 1019AH receiver, along with a plasma TV and sound bar. I currently have the receiver set to HDMI through, with the HDMI output from the receiver split so the TV receives the video signal through HDMI and the sound bar gets the audio through Toslink optical. I would also like to play sound through some surround speakers, but the HDMI Through setting seems to disable the speaker connections. Is there a way to play the audio this way using my current components?
